The Star SP512 with tear bar combines renowned reliability and a multitude of high-end features into a compact, value-driven solution. Features such as the logic seeking mechanism, new high-speed printhead and the latest electronics contribute to the high print speed of the SP512. This print speed of over 4 lines per second enables the SP512 to outperform the competitors in its class. The hinged cover of the SP512, with its integrated 'rain channel', protects the printer form liquid spills and other debris. Protection from the elements and the single color highlight feature of the SP512 series provide an excellent solution for food service and kitchen applications where airborne debris is a sure factor.
